head to head
Neither is meaningfully harder - they pose close to the same test. The widest gap is reads, and it is a single point.

Execution · Practiced Mastery
Aiming banked bubble shots quickly while planning chain clears.

Execution · Practiced Mastery
Open-world Stone Age action game about hunting and conquering tribal outposts with tamed beasts.
Bust-a-Move 4 leans Execution (Practiced Mastery); Far Cry Primal leans Execution (Practiced Mastery).
Same score on execution - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-a-Move 4
Precise bubble aiming and bank shots under time pressure
Far Cry Primal
Bow aim, melee timing, beast control under pressure
Bust-a-Move 4 leans a little harder on reads, though the gap is small.
Bust-a-Move 4
Versus mode allows mild human pressure timing
Far Cry Primal
Scripted tribal AI never models the player
Same score on variance - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-a-Move 4
Bubble colour feed is random but bounded
Far Cry Primal
Wildlife encounters and patrol spawns are random
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Bust-a-Move 4
Clearing patterns and pulley setups have known solutions
Far Cry Primal
Outpost routes, crafting economy, beast taming order
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
